USI Certification Review

Front

Resolution that measures how closely lines can be resolved in an image.

Back

Spatial Resolution

Front

The ability of a sensor to detect differences in energy magnitude or intensity.

Back

Radiometric Resolution

Front

The way a remote imaging sensor responds to different wavelengths of light: high to low.

Back

Spectral Resolution

Front

The frequency at which images are captured for a specific location on the earth.

Back

Temporal Resolution

Front

LOW spectral resolution means that the sensor distinguishes between very narrow bands of wavelength, while HIGH spectral resolution means the sensor records the energy in a wide band of wavelengths as a single measurement.

Back

False

Front

The bending of light as it passes through the atmosphere, causing distortions in the image called refraction

Back

True

Front

The measure of the amount of radiation leaving or arriving at a surface, in all directions is called radiance.

Back

True

Front

Which type of sensor relies on natural sources of energy, such as sunlight, to create images?

Back

Passive

Front

Which type of sensor emits its own energy and measures the energy that is reflected or scattered back from the target object or surface?

Back

Active

Front

Which imaging technique displays the temperature difference between two objects or regions in an image? Options: Isometric IR, Isothermal IR, Radiometric IR, Radio Station IR

Back

Isothermal IR
